Synopsis : To develop a stainless steel with excellent oxidation resistance for the metallic substrate of the catalytic converter, influences of La and Zr on the oxidation resistance of 20%Cr-5%Al steel foil and toughness of the hot-rolled sheet of the steel were investigated. La addition combined with Zr increases the oxidation resistance of the steel foil more than La sole addition or La addition combined with Ti, and the Zr addition equal to 1 at Zr/(C+N) in the atomic percent ratio improves the toughness of the hot-rolled sheet of 20%Cr-5%Al-La steel. The newly developed stainless steel, RIVER LITE 20-5USR (20%Cr-5%Al-La-Zr steel) has more excellent oxidation resistance at high temperature compared with conventional steel. |
